Water Softener Plant

A water softener is a unit that is used to soften water, by removing the minerals that cause the water to be hard. When water is referred to as 'hard' this simply means, that it contains more minerals than ordinary water. The degree of hardness of the water increases, when more calcium and magnesium dissolves. Magnesium and calcium are positively charged ions. Because of their presence, other positively charged ions will dissolve less easily in hard water than in water that does not contain calcium and magnesium. Water softening can prevent these negative effects.

Process

Softening is the ion exchange process, it is done through resin, the most common and probably the easiest method of removing hardness) from water and suitable for utility purpose.
As the name implies ion exchange is a process in which undesirable ions are exchanged for more desirable ions.

The softening process consists of passing raw water containing hardness through a bed of cation resin in sodium form.The hardness ions calcium and magnesium are taken up by resin and in exchange, the sodium ions are relinquished from the resin. This is called the service cycle, where the hard water is being softened
